(Shown below)

Step-by-step explanation:

The Mean, AKA the average is all of the numbers added up, then divided by how many numbers there were. For example, take this data set:

3, 5, 10, 6, 5, 5

We add up all of the numbers:

3 + 5 + 10 + 6 + 1 + 5 + 5 = 35

Now, we divide by how many numbers there were. Since there were 7 numbers, we do:

$\frac{35}{7} = 5$

Therefore, 5 is our Mean.

Next up, the Median. Median is just the number in the middle of the data set, but we have to put it from least to greatest. Here it is again:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

As you can see, the 5 is in the middle, so it is our Median.

Now the Mode. The Mode is number that occurs most often. Again, it's easier to put the numbers from least to greatest. The data set:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

So, the 5 is the Mode because it occurs thrice, while the other numbers only occur once. Remember the Mode is what the number is, not how many times it repeats.

Lastly, the Range. The Range is just the difference of the largest number to the smallest number. This one also requires to be from least to greatest.

1, 3, 5, 5, 5, 6, 10

10 - 1 = 9

Therefore, the Range of the data set is 9. I hope this helps you!
